ExOne's Metal 3D Printing Adoption Center outside Pittsburgh features about a dozen furnaces, including a new all-metal Elnik MIM3045 debind and sinter furnace (shown above).

ExOne June 16 announced it has surpassed delivery of 2 million metal parts to customers worldwide and has added two new printers to its lineup for dedicated production of stainless-steel parts.

A global leader in industrial sand and metal 3D printers using binder jetting technology, ExOne's metal 3D production facility has been in continuous operation since 2005 and has successfully reached the 2 million parts milestone.

Widely regarded as the fastest method of metal 3D printing, the binder jetting process employed by ExOne is very similar to inkjet printers – an industrial "inkjet" printhead selectively deposits a binder into a bed of powder particles creating a solid part, one thin layer at a time. Binder jetting can create 3D objects in metal, sand, ceramic, or other 3D material powders.

After metals are printed, the final part must be sintered in a furnace to fuse the particles together into a lightweight, highly dense solid object.


Along with the 2-million-part milestone, the company has launched two new X1 25Pro binder jet printers fully dedicated to producing stainless steel parts for industrial customers and service bureaus. These printers feature Triple ACT, the company's patented Triple Advanced Compaction Technology, which uses an exclusive method of dispensing, spreading, and compacting ultra-fine metal powders during the binder jet 3D printing process.

The Pennsylvania-based component manufacturer will also continue offering its proprietary X1 Metal 420i – a metal matrix composite made up of 60% 420 stainless steel that is 40% infiltrated with bronze, one of the earliest products offered by ExOne.

Pioneering 3D printing since 1995, ExOne has persisted and managed to bring to today a highly functional and efficient metallic printing process that very well could be the method of large-scale manufacturing for the future.

Metal Tech News congratulates ExOne on their achievement and hopes to see many such successes in the future!
